GFS Most Recent Sea Level Pressure and 325 Kelvin Potential Vorticity

This map is an overlay of the most recent GFS maps of sea level pressure and mid-tropopshere potential vorticity. It is used to diagnose the depth and tilt of vorticies, including tropical cyclones and potential tropical cyclones.
